Sheet feeding device and image forming apparatus

Abstract

A sheet feeding device includes a sheet accommodation portion that accommodates piled sheets, and a guide formed by bending a plate-shaped member and having an abutting surface that abuts on the piled sheets so as to restrict a position of the piled sheets. An inclined surface is formed in a top end portion of the abutting surface. Preferably, one or more than one protruding strip is provided to the guide on a surface on a side where the abutting surface is formed along a direction in which the sheets are inserted into the sheet accommodation portion.

     3. The sheet feeding device according to  claim 1 , wherein:
 the abutting surface extends in a vertical direction and the guide has a top end surface that extends in a direction almost orthogonal to the abutting surface; and 
 the inclined surface is positioned between the top end surface and the abutting surface. 
 
   
   
     4. The sheet feeding device according to  claim 3 , wherein:
 the inclined surface is provided with one or more than one protruding strip along a direction in which the sheets are inserted into the sheet accommodation portion. 
 
   
   
     5. The sheet feeding device according to  claim 4 , wherein:
 the protruding strip is provided across at least a part of the top end surface and the abutting surface. 
 
   
   
     6. The sheet feeding device according to  claim 1 , wherein:
 a side end of the guide is bent in a direction so as not to abut on the sheets. 
 
   
   
     7. The sheet feeding device according to  claim 6 , wherein:
 side ends of the inclined surface and the abutting surface are bent in the direction so as not to abut on the sheets. 
 
   
   
     8. The sheet feeding device according to  claim 1 , wherein:
 the sheet accommodation portion includes a bottom plate disposed in a horizontal posture and plural side plates provided perpendicularly to the bottom plate, and opens at a top surface; 
 the bottom plate is provided with a first engagement portion and each side plate is provided with a second engagement portion at a top edge thereof; and 
 the abutting surface of the guide extends in a vertical direction, a third engagement portion that engages with the first engagement portion is provided to a bottom end of the guide, and a fourth engagement portion that engages with the second engagement portion is provided at a top end of the guide. 
 
   
   
     9. The sheet feeding device according to  claim 8 , wherein:
 the first engagement portion and the second engagement portion are provided in a plural form at different positions. 
 
   
   
     10. The sheet feeding device according to  claim 8 , wherein:
 the first engagement portion is a slit and the third engagement portion is an inserting portion inserted into the slit. 
 
   
   
     11. The sheet feeding device according to  claim 8 , wherein:
 the second engagement portion is an engagement protrusion and the fourth engagement portion is a hole into which the engagement protrusion is fit. 
 
   
   
     12. An image forming apparatus, comprising:
 an apparatus main body that performs an image forming operation for sheets; and 
 a sheet feeding device that feeds the sheets to the apparatus main body, 
 wherein the sheet feeding device includes: 
 a sheet accommodation portion that accommodates piled sheets; and 
 a guide formed by bending a plate-shaped member and having an abutting surface that abuts on the piled sheets so as to restrict a position of the piled sheets, and 
 wherein an inclined surface is formed in a top end portion of the abutting surface. 
 
   
   
     13. The image forming apparatus according to  claim 12 , wherein:
 one or more than one protruding strip is provided to the guide on a surface on a side where the abutting surface is formed along a direction in which the sheets are inserted into the sheet accommodation portion. 
 
   
   
     14. The image forming apparatus according to  claim 12 , wherein:
 a side end of the guide is bent in a direction so as not to abut on the sheets. 
 
   
   
     15. The image forming apparatus according to  claim 12 , wherein:
 the sheet accommodation portion includes a bottom plate disposed in a horizontal posture and plural side plates provided perpendicularly to the bottom plate, and opens at a top surface; 
 the bottom plate is provided with a first engagement portion and each side plate is provided with a second engagement portion at a top edge thereof; and 
 the abutting surface of the guide extends in a vertical direction, a third engagement portion that engages with the first engagement portion is provided to a bottom end of the guide, and a fourth engagement portion that engages with the second engagement portion is provided at a top end of the guide.
